The reactants are HCl and NaOH.
H2O + NaCl
The reactants are on the LEFT side of the arrow; the products are on the RIGHT side of the arrow. Note: "Reactants"=what is reacting; what you are starting with. "Products"=something you create. Thus, hydrochloric acid and sodium hydroxide are the reactants in this equation.
Yes
This neutralization reaction is:NaOH + HCl = NaCl + H2O
The reactants are HCl and NaOH.
NaCl doesn't undergo a chemical reaction with NaOH, so you wouldn't be able to tell.
Both have the same cation.
H2O + NaCl
The reactants are on the LEFT side of the arrow; the products are on the RIGHT side of the arrow. Note: "Reactants"=what is reacting; what you are starting with. "Products"=something you create. Thus, hydrochloric acid and sodium hydroxide are the reactants in this equation.
A Double displacement reaction or Neutralization reaction
Yes
This neutralization reaction is:NaOH + HCl = NaCl + H2O
An acid-base reaction yielding a salt and water.
The reaction is:NaOH + HCl = NaCl + H2O
Copper hydroxide is the precipitate.
NaCl(s) + C2H5OH(l) --> NaOH(aq) + C2H5Cl(aq)
